What is a money market account?

A money market account is a federally insured deposit account from a bank or credit union. You may also hear it called a money market deposit account, or MMDA. It can help savers earn a competitive return while keeping funds accessible, with FDIC or NCUA coverage up to applicable limits.

Understand what a money market account is

Money market accounts combine features of savings and checking accounts. They can earn interest like savings accounts while offering easier access to your money. This makes them a good option if you want to grow your savings and keep your funds within reach.

Federal insurance is a core part of what makes these accounts secure. Deposits at banks are insured by the FDIC, and deposits at credit unions are protected by the NCUA. Both cover up to $250,000 per depositor, per institution, per ownership category. That means your principal stays safe even if the bank or credit union fails, which offers real peace of mind if security matters as much to you as yield.

How do money market accounts work?

Money market accounts earn interest on your deposits, at a rate that is usually variable. Some accounts offer tiered rates based on your account balance. Understanding how these accounts work day-to-day can help you maximize the benefits while avoiding potential pitfalls.

• Interest: Your deposits earn interest. A higher balance may qualify for a higher annual percentage yield (APY), depending on the account. For example, an account might pay one rate on balances up to $10,000 and a higher rate on amounts above that threshold. Because rates are variable, they can change based on broader market conditions and interest rate movements.
• Access: Many accounts include check-writing privileges, a debit card and ATM access. These tools help you access your funds when needed and without having to transfer money to a checking account first.
• Transaction limits: Some financial institutions still limit certain withdrawals or transfers to six per month.
• Limit exceptions: ATM withdrawals and in-person withdrawals usually do not count toward transaction limits.
• Opening and balance requirements: You may need a minimum deposit to open the account. You may also need to maintain a minimum balance to avoid fees or earn the stated APY.

Compare money market accounts vs. savings accounts

Money market accounts often provide check-writing and debit card access, while traditional savings accounts generally do not. They also tend to require higher minimum balances.

Here are a few key differences:

• Interest rates: Money market accounts historically paid more than traditional savings accounts. Today, rates vary by institution. A high-yield savings account may match or exceed a money market account’s rate.
• Minimum balances: Money market accounts typically require more money to open and maintain. A savings account may be sufficient if you want a lower or no minimum balance.
• Access: Money market accounts often include check-writing and debit card access. Traditional savings accounts generally do not.
• Deposit insurance: Eligible deposits in both account types are insured up to $250,000 per depositor, per institution and per ownership category. The FDIC covers bank deposits, while the NCUA covers credit union deposits.

Distinguish money market accounts from money market funds

A money market fund is a type of mutual fund that invests in short-term, low-risk securities, such as Treasury bills and commercial paper. It is an investment product. In contrast, a money market account is a bank deposit account.

Here is how the two products compare:

• Insurance and risk: Eligible deposits in money market accounts are federally insured up to applicable limits. Money market funds are not federally insured and can fluctuate in value.
• Where they are available: You open a money market account at a bank or credit union. You purchase a money market fund through a brokerage firm.
• Yield and purpose: A money market fund may offer a higher potential yield, but it carries investment risk. A money market account prioritizes capital preservation and access to savings.

Use this checklist to decide which product may be right for you:

• Do you need federal deposit insurance? A money market account may be a better fit.
• Are you comfortable with potential changes in value? A money market fund may fit your investment goals.
• Do you need check-writing or debit card access? Money market accounts commonly offer these features, while money market funds do not.
• Is the money for short-term savings or investing? A money market account may suit short-term savings. A money market fund may suit investment purposes.

Compare money market accounts vs. CDs

Certificates of deposit (CDs) require you to lock in funds for a set term in exchange for a fixed interest rate. Money market accounts offer ongoing access with variable rates.

Here are a few other ways they differ:

• Access: CDs hold your money until the term ends. Money market accounts let you make withdrawals while the account remains open.
• Rates and penalties: CDs often offer higher rates than money market accounts, though rates vary by institution and term. Withdrawing from a CD before maturity usually results in an early withdrawal penalty.
• Ideal uses: Money market accounts allow withdrawals without an early withdrawal penalty, though transaction limits or account fees may apply. They may be a better fit for emergency funds or savings you may need soon. In contrast, CDs are good for money that you don’t plan to touch for a set period.
• Deposit insurance: Eligible deposits in both CDs and money market accounts are insured up to $250,000 per depositor, per institution and per ownership category when held at an FDIC-insured bank or NCUA-insured credit union.

Evaluate the benefits of a money market account

Money market accounts can offer strong returns, security and convenient access for short-term savings.

• Higher interest potential: Rates may be higher than traditional savings account rates, helping your money grow faster.
• Safety and security: Eligible deposits are insured up to $250,000 per depositor, per institution and per ownership category by the FDIC at banks or the NCUA at credit unions.
• Flexible access: Checks, a debit card and ATM access can provide liquidity without early withdrawal penalties.
• Ideal for short-term goals: These accounts can hold emergency funds, savings for a large purchase or cash reserves before retirement. If you’re trying to determine how much cash to hold in your portfolio, a money market account offers a secure, accessible place for those reserve funds.

Is a money market account right for you?

A money market account may fit your needs if you want competitive interest, federal deposit protection and occasional access to your savings. Before opening one, review the account’s requirements and ask yourself:

• Savings goal: Are you building an emergency fund or saving for a short-term goal?
• Balance requirements: Can you meet the opening deposit and minimum balance needed to avoid monthly fees or earn the stated APY?
• Fees: Have you compared monthly maintenance, excess transaction and ATM fees across institutions?
• Access: Do you need occasional access through checks, a debit card or an ATM, and have you reviewed any transaction limits?
• Rate changes: Are you comfortable with a variable interest rate that can rise or fall with market conditions?
• Deposit protection: Is the account held at an FDIC-insured bank or NCUA-insured credit union?

For cautious savers: A money market account can offer a low-risk place for an emergency fund, with competitive interest, access to your money and federal insurance protection on eligible deposits.

For emerging planners: It can be a next step beyond a basic savings account when your balance is growing and you are ready to seek a higher rate.

For retirement preparers: It can provide an accessible place for cash reserves without locking the money in a CD. The Retirement Select Money Market Account is designed for this purpose. It gives you flexibility as you manage your retirement income.
